No mention of Landspace who have already conducted hopper tests ?

FAA gives SpaceX a bunch of homework to do before Starship flies again

Oneman2Many

My issues is that effectly SpaceX are self-certifying the clearance. I don't have any knowledge of what the behind the scenes discussions are but SpaceX and FAA have said many times that they are continously in contact so I doubt the publish report is the first itteration of it. How many times did FAA push back and get SpaceX to make changes ?

Oneman2Many

FAA didn't come up with. That is what SpaceX told the FAA what they plan to do There will be more details that SpaceX will have given to FAA.

Oneman2Many

As per last time, FAA didn't write the report or really have any input. The report is spacex reporting on issues they found and will correct and I suspect most of have already been implemented as there are things like design changes which would take months to implement (or years if you are Boeing). All the FAA are doing is agreeing with SpaceX findings. I can understand why is works this way as SpaceX are the SME on Starship so will know the most about what happened and how to prevent it in future but it does seem to make FAA rather toothless.

Who is telling SpaceX where the frontline is and where it should and shouldn't work ?

As for the terminals, apparently supplied via UAE but mostly likely that is BS.

Re: Hmm ...

VeraCrypt doesn't support Active Directory, AFIAK it doesn't offer any support for central key storage or passwords. Probably a major requirement for most enterprises.

I suspect as well that you can access TPM even with it integrated but you are looking at some pretty specialist tools. Looks at what they managed to do with the locked iPhone from the US terrorist.

Re: A brilliant testament to analysis

This isn't a logon PIN, this is a bitlocker PIN which is different and I suspect no organisations have it switch on.

Re: A brilliant testament to analysis

You don't need GPO setting to show the option but yes the user will need to be a local admin which they aren't on most enterprise workstations.

It does need access to the LPC connector, the laptop used had the lanes exposed on a unused connector, other laptops may need chip to be de-soldered to gain access which to do be honest isn't going to stop a determined and semi-skilled bad actor.

It also needs a discrete TPM chip, which has been integrated with CPU since 6th gen on Intel back in 2015 (wonder why a 10 year old laptop was used ?).

Finally if you are worried then you can create a Bitlocker PIN which stops the attack however I suspect the majority of users don't do that.

Suffice to say that it goes to show that if somebody gains physical access to your device then it will be vulnerable.

Rocket Lab is a David among Goliaths in the space race

Re: Which rocket?

Not sure what your point is ?

Booster and Starship both exploded over the Gulf, not part of any national park. Stage 0 did rain debries down in national park but it wasn't the rocket.

I expect more from Peter Beck, he's had great interviews with Tim Dodd and NSF amongst other. He seems like a nice guy and obviously passionate about his company and rockets in general so I wasn't expected snidey remarks from him especially ones that are facturally incorrect.

Re: Prudent

Who says it won't be pushed out, HLS is only one of many issues that is holding the program up. SLS, Spacesuits, Orion capsule and I'm sure many others.

I assume you were joking about 'NASA had a chat with second place finisher' ? The major partner of that bid has left the consortium, I assume having lost the original competition there has been zero further development unlike SpaceX which would have carried on regardless of winning the contract on not. The contract awarded for 2nd lander is for 2028, it very unlikely they can pull ahead to any time sooner and I'm not even holding my breath about them making the 2028 schedule being a multi company partnership which historically has been a recipe for delays especially taking into account the members involved. So not sure where you get the idea that its some sort of race ?

I am not sure where you think Astrobotic recent lunar attempt comes into it. Its great the work they are doing but human flight is on a different scale to their plans. Assuming they leave the launch services to an established player (SLS, Starship, mayby New Glen) the lander part is billions of dollars to develop and with 2 human rated systems under development is there space for a 3rd player ?

As for Dreamchaser, I am guessing you are confused by its scope and where it would fit into Artimes program. Right now its being developed for cargo. They do have a contract (manybe ?) and potentially funding to provide crew transport services to LEO for Blue Reef so no trips to the moon. According to this site the first flight doesn't even had a date but won't be before 2029,

Re: Prudent

Where do you draw the line. SpaceX are talking about V2 and V3, does that mean they should wait even though V1 can still produce valid results ?

As for NASA, they have given up on 2025 or even 2026 for Artimes 3. I honestly won't be shocked if the delay landing to 2028 and Artimes 4.

As Broadcom nukes VMware's channel, the big winner is set to be Nutanix

Oneman2Many

KVM as the hypervisor is fine but you will need management tools and security hardening for on prem enterprise hosting.

Oneman2Many

I'm pretty sure that anybody who has been in the industry more than 5 minutes knew this was going to happen based on Broadcoms previous track record. Even before the aquisition, the change to core based licensing pushed costs up but as soon as there was whispers of Broadcom being in the running we knew the writing was on the wall for VMWare. As we have been banging on to our developers and vendors for the last 5 years, the future is CaaS and the hosting solution was never going to be Tanzu.

Its a shame, they have some solid products and there is nothing else that has management tools and 3rd party support that scale for enterprise hosting. Nutanix is OK for SMB but falls shorts when scaled up.

Re: Starlink subsidy

SpaceX have stated that with the laser links they have global coverage. They looking at more ground stations to reduce latacy and improve bandwidth.

SpaceX guy at the astro awards said they plan on having complete coverage by the end of this year, I assume he meant that mainland US will have 24x7 coverage not global.

Broadcom ditches VMware Cloud Service Providers

Re: The End

The management is not even close what VMWare and shed load of 3rd parties offer. But upcoming pricing changes and broadcoms past history is a big incentive to get off VMWare. TBH, this is a good stick to beat your users to move to CaaS and get off Windows (mainly) and Linux.

Hubble Space Telescope is back in the game after NASA fixes gyro glitch

Re: Jared wants to help

Think the plan for the second mission is to test out EVA. Then work with NASA for a.repair on the next mission. Boosting orbit should be pretty easy. Replacing the gyroscopics will be difficult. There aren't any handholds and they don't have an arm to help them on EVA.

Hubble science instruments still out after going down 3 times in a week

Oneman2Many

Issacman is looking at this as part of Polaris missions. NASA had signed off on a feasibility study last year but not heard of any updates since.

First flight is due in first half of 2024 and they are planning a EVA so will see how feasible a service mission from a dragon capsule would be. Boosting the orbit shouldn't be an issue, NASA installed a mating ring on the last shuttle service to make that easier. The lack of a robotic arm apparently is a major issue for changing the gyros as there aren't any handgrips on Hubble.

BTW, this would be all be paid for Issacman and potentially SpaceX and any 3rd parties as companies such as Axiom who may be able to assist.

Elon Musk's ambitions for Starship soar high while reality waits on launchpad

Beem many years ago that lunar lander variant has landing legs. They will need to ensure that it lands somewhere relativily flat. Be interesting to see if landing engines will be at the top to avoid kicking up debris or at the bottom.

Re: Most powerful

3 engines shutdown before takeoff leaving 30 engines running at 90% power. With each engine rated at approx 230 Tons that give about 60MN. So yes, the most powerful rocket to take off.

Re: arrggh

A few years ago but I converted about 50 Asus netbooks for local primary school to ChromeOS. The WiFi cards didn't work but I found compatible ones for a couple of quid each on fleabay. AFAIK they are still using a few of them today. Flex probably is a lot easier to install than the workarounds I had to use back then.

SpaceX's second attempt at orbital Starship launch ends in fireball

Oneman2Many

Re: Complexity ≠ Reliability

Yeah, its not clamp at launch time, relies on gravity. Engines start at 50% which is not enough lift off and then throttle up.

STS used explosive bolts and they had multiple instances of the bolds not cleanly separating correctly but fortunately not enough of an issue to stop the launch though once the SRB were lit there was no turning them off.

Re: Why all the cheering before the 10 second countdown?

The Van actually is actually owned by BocaChicaGirl (Mary) but is used by NSF. They have a video of them returning to the van. Its a right off and I'm pretty sure its not covered by insurance, lol. To be honest its a pretty old Dodge minivan and wasn't worth much.

Re: restart supplies

Yeah, they use an electric based system. Probably sensible if a return trip to Mars is going to need multiple restarts.

You should probably watch Tim Dodds video on how to start a rocket engine.

SpaceX's Falcon Heavy rocket launches after three-year hiatus with secret US sats

Re: I don’t agree, but….

Even if there are enough missions and money, Boeing and the cartel can barely meet 1 launch a year cadence.

Oneman2Many

I'll bite though I probably shouldn't.

SLS Block 1 has a 95T LEO capability. FH is around 63T.

Europa Clipper which was due to launch on SLS but has been switched to FH is probably a good use case for comparison. There were 3 factors which were cited,

- FH has enough performance to avoid gravity assist from Venus, something that Delta Heavy would need and the reason why DH couldn't be used.

- There is no capacity from Boeing for supplying the launch capability for a 2025 (at the latest) launch. All SLS capacity is allocated to Airtimes program. FH will take an additional year to get there which means it needs to launch in 2023 (it could launch in 2024 but call it 2023 to allow a performance buffer) but that is something that SpaceX can support.

- There is a potential vibration issue caused by the SRB. Boeing is stating one value but NASA's own wind tunnel testing is coming up with a different value. NASA has other SRB data from the shuttle era which supports their worries as well but didn't factor that into this report. Without actual launch data its impossible to discount the issue.

ARS Tech which is pretty reputable site has a good article on the switch. According to the article a fully expended FH launch is costing around $178m and there is a white house comment that SLS launch is $2bn excluding development in one of the linked articles. I was being pretty generous saying its 'only' a billion as that is what is in wiki.

https://arstechnica.com/science/2019/11/the-white-house-puts-a-price-on-the-sls-rocket-and-its-a-lot/

Don't get me wrong here, I think SLS is the best option for Artemis. Its a direct flight, no messing about transferring crew, no in-flight refuelling, most proven technology and a bunch of other reasons. But as a general non-crew launch vehicle its a bit of a non-starter.

Oneman2Many

The SLS Wiki article SLS is over $1bn per launch, that is excluding all the development and maintenance costs. Falcon heavy fully expended is $150m for 2/3 of the LEO payload capacity. Of course there are missions that can't be done by FH due to fairing size limitations, lack of vertical integration and other capacity limitations.

Starlink, shot by both sides in Ukrainian fracas, lives to fight on

Oneman2Many

Didn't mention the option that the backend systems are being hacked. Seeing as starlink knows where the terminals are it would be possible to selectively disable them selectively. In the list of possibility far more likely than Elon telling starlink to block Ukraine.

SpaceX reportedly fed up with providing free Starlink to Ukraine

Oneman2Many

Nobody is saying they invented the tech, just like Apple they created the market. Tesla ran at a huge loss, much like SpaceX, almost went bust more than once and most people would have given up.

Peering really isn't free or even cheap.

I have seen the data but I get the feeling they are only using a few ground stations which probably isn't helping. I haven't seen too many complaints about speed, seems to be jamming seems to be the main issue

Anyway, looks like he will continue to fund the donations for the time being.

Scavenging pad 39A

Re: Believe it when I see it

Forgot add, one hiccup is they will need approval for each type of aircraft, could be time consuming.

Oneman2Many

Re: Believe it when I see it

They have been testing with Delta and I believe USAF. They have also been testing with F9 missions so I would think technically they are confident.

At the they don't have laser link work AFAIK so the plane has to be within 500 miles of a ground station which I thought might be an issue for trans Pacific flight ? Maybe sats in a higher orbit have a larger radius of coverage.

SpaceX launches first totally private mission to the International Space Station

Re: dependencies

I believe the figure is around $10m but don't know if that is split between NASA and the other agencies. There is a breakdown somewhere, meal costs are $2k per day. Life support and toilet are around 20k per day (seems cheap). AFAIK, I don't believe Axiom have taken any supplies up with them.
